SHEET-FLUE 'RA NGE.

SPECIFICATION forming part of Letters Patent No. 589,882, datedSeptember 14, 1897.

Application filed March 11, 1897- To all whom it may concern:

Be it known that I, STEBBINS S. WEBBER, a citizen of the United States,residing in La Porte, in the county of La Porto and State of Indiana,have invented a new and useful Improvement in Sheet-Flue Ranges, ofwhich In that class of ranges known as sheetflue ranges the usual courseof the heat-currents or products of combustion from the fire is over theforward portion of the oven, down through the forward portion of thesheet-flue, thence under the forward portion of the oven, and thence tothe exit-pipe at the rear of the stove. This produces an uneventemperature in different parts of the oven, the rear port-ions beinginadequately heated, and such result is due to the fact that theheat-currents take the shortest course from the fire to the exit-pipe,and the course described is rendered the shortest by reason of thepresence in the bottom flue of a deflector arranged between thesheet-flue and the exit and extending from the rear wall of the bottomflue toward the front wall in such manner as to compel the currents topass around the front end of this deflector.

The object of my invention is to obviate this uneven heating of theoven, and I accomplish it by shutting off or closing the forward portionof the sheet-flue by means of a will compel the heat-currents when theyreach the sheet-flue to move towardthe rear of the oven. Theheat-currents will also by reason of this device move over-nearly theentire upper surface of the oven instead of being diverted toward thefront, as in the ordinary construction, and in this manner I insure theheating of the rear portions of the oven upon the top, side, and bottomequally with the front portions.

The nature of my invention will be fully understood from theaccompanying draw ings, in which-- Figure 1 is a plan view of a stoveembodying my invention; and Fig. 2 is a vertical section thereof, takenin the plane of the sheetflue.

Serial No. 626,954. (No model.)

In said drawings, A represents the top; 13, the fire-pot; O, the oven 5D, the exit-pipe; E, the holes for the kettles; F, the sheet-flue 3 G,the flue over the oven and between it and the top of the stove, and Hthe bottom fine. In the latter is the guard or deflector J, the positionof which is fully shown, particularly at Fig. 1. These parts are allconstructed in the ordinary manner.

In the sheet-flue F, I place my invention, which in the form illustratedconsists of a plate K, resting at one edge upon the top of the oven andextending over to the outside wall of the flue, and the inner portion ofthe plate K, I prefer to bend downward, as best shown at Fig. 2, so thatwhile it may serve to compel the heat-currents to move toward the rearof the stove it will accomplish that object without forcing them to seekthe rear of the stove while moving over the top of the oven, at least toany harmful extent. The plate K is provided with a slot K through whicha retaining-screw K may be passed, and an operating-rod K is attached toit and extends out in front of the stove, so that, if desired, theplaternay be moved inward and thus open the front corner of thesheet-flue to the entrance of the heat-currents. Good results will beobtained in either way of using it. Instead of making the plate movableit may be made permanent, if desired.

It will be seen that by the use of this device the heat will pass evenlyover all parts of the top of the oven, that in passing down thesheet-flue it will seek the rear half thereof, and when it issues intothe bottom flue it will be under the rear corner of the oven, which hasheretofore been very inadequately heated.

While I have shown a sliding plate for accomplishing these results, itwill be understood that I do not wish to be limited either to a slidingor stationary plate, as obviously the same result may be accomplished bymany different constructions, all of which are in the province of myinvention.

The arrows in the drawings indicate the direction of the heat-currents.

I claim-- The combination with the oven of a sheetfront thereof andhaving a downward and flue cooking-range, of means whereby the rearwardextension K, substantially as speciproduots of combustion may be allowedto pass fied. I

over substantially the entire surface of the STEBBINS' S. WEBBER. 5 ovenand be then deflected to the rear'of the /Vitnesses:
